Figure 7. Streambank soil types of the Bourbeuse River watershed habitat assessment sites. Summarized is the percentage (total soil type/total sampled soil layers) X 100] found within sampled streambank soil layers of the shown hydrologic units. Soil layers within the streambank were categorized by starting at the water line of the streambank to the top. See primary and secondary despriptors of the soil type.
Primary soil descriptors are gravel (G), sand (S), silt (M), clay(C), organic (O), and peat (Pt). The secondary descriptors are well graded (W), poorly graded (P), with nonplastic fines (M), with plastic fines (C), or low plastic fines (L), and of high plasticity (H) (Olson 1983). BR--bedrock
